Make a précis of the given passage in about one-third of its original length. Supply a suitable title: The ‘media’ is the fourth estate in a democracy. People form the government by handing over their mandate. The media determines the quality of the governance and set the agenda for governance. Media has rightly been described as ‘Vox Populi’, voice of the people. With internet having been added as an organ of the media, the media has demolished the confines of border lines. The globalization of media has made the role of media multi-dimensional. Apart from carrying the news to the public, it brings enlightenment to the public too. The enlightened citizenry is the most valuable assets of a democracy. Investigative Journalism and sting operations are the recent forms of journalism. Though beneficial, these practices are embroiled in controversy. They are sorts of trial by media. Take Arushi murder case. They said whatever their investigations revealed on day-to-day basis. Doubt was cast on everyone known to the Talwars. Their sympathisers turned away. The pity is that once an incident involving a person takes place, the media, electronic and print, swing into action. They virtually leave little for the prosecution and the courts. The over enthusiastic media performs the role of prosecution and the judiciary at the same time. It cannot be denied that no one is above law and therefore, mass media should not be allowed to go unchecked. Freedom of speech and expression enshrined in article 19 (1) of the Indian Constitution is restricted by Article 19(2) in the interest of, inter alia sovereignty and integrity of the country. Apart from restriction of speech the Constitution of India guarantees the fundamental right to privacy under Article 21 of the Constitution. Over-activism of the media is hindrance to citizen’s right to privacy and right to life. There is no doubt that right to privacy is an essential ingredient of personal liberty. In their various observations the courts have drawn the attention of media in the following words “abysmal levels to which the norms of journalism have drifted.” In another case they blamed the media interfering with the admistration of justice.
